Abstract
Implementations of a needle loader and related methods are provided. The needle loader comprises a housing, a movable arm disposed within the housing, and a needle mount defined on the movable arm to releasably attach to an arced suturing needle. The needle loader further includes an arced needle releasably attached to the needle mount. The needle can be held in place on the needle mount by way of an interference fit. The needle mount can be defined on a surface of the movable arm that faces an arced needle track of a suturing device when loading an arced suturing needle in the needle track of the suturing device.

1-20. (canceled)
A device for loading at least a portion of a suturing needle into a suturing device, comprising:
- a mount defining a needle engagement portion to releasably hold a suturing needle, wherein:
- the mount is configured to slide along a first direction from a first position wherein the at least a portion of the suturing needle is out of alignment with a needle pathway of a suturing device, to a second position wherein the at least a portion of the suturing needle is aligned with the needle pathway of the suturing device;
- the mount is configured to slide along a portion of the suturing device along the first direction as the mount and the at least a portion of the suturing needle are advanced from the first position to the second position;
- and
- the mount and the at least a portion of the suturing needle are configured to deflect along a second direction that is different from the first direction as the mount and the at least a portion of the suturing needle are slid from the first position to the second position.
A device for loading at least a portion of a suturing needle into a suturing device, comprising:
- a mount defining a needle engagement portion to releasably hold a suturing needle;
- a flexible elongate shaft coupled to and extending proximally from the mount, the flexible elongate shaft having an elongate cross-section, the elongate cross-section having a first transverse dimension along a first transverse direction that is parallel to a needle pathway of a suturing device, and a second transverse dimension orthogonal to the first transverse dimension along a second transverse direction, wherein:
- the first transverse dimension is larger than the second transverse dimension to permit the flexible elongate shaft to flex more easily along the second transverse direction than the first transverse direction;
- the mount and flexible elongate shaft are configured to slide along a first direction from a first position wherein the at least a portion of the suturing needle is out of alignment with the needle pathway of the suturing device, to a second position wherein the at least a portion of the suturing needle is aligned with the needle pathway of the suturing device;
- and
- the relative position of the mount to the at least a portion of the suturing needle does not change as the mount and flexible elongate shaft move from the first position to the second position.
